The Slovenian Basin is a Mesozoic deep-water paleogeographic unit, located along the border between the eastern Southern Alps and the Dinarides, that records geodynamic signals from the opening of both the Piedmont-Liguria and the Neotethys oceanic domains. In the Middle Jurassic, it was bordered by the Dinaric (Adriatic) Carbonate Platform to the south and the Julian High submarine plateau to the north. The southern margin of the basin is characterized by a several tens of meters thick sedimentary sequence of Bajocian-Bathonian (Callovian?) age that is dominated by limestone megabreccia shed from the Dinaric Carbonate Platform, sedimented by debris-flows in a toe-of-slope sedimentary environment. It is accompanied by rud/grain/packstone beds sedimented via (high-density) turbidity-flows. This megabreccia unit represents the proximal equivalent of the lower resedimented limestones of the Tolmin Formation. The matrix within lithoclasts indicates resedimentation from ooidal shoals and the erosion of basinal and slope sediments. Lithoclasts are of Norian to Lower Jurassic age, and originated from (A) platform margin carbonates, i.e. Triassic marginal reef and Lower Jurassic sand-shoal limestones, (B) deep open-shelf or slope coarse bioclastic limestones, and (C) older basinal rocks. The lithoclast analysis enables the reconstruction of the platform-basin transitional zone that is not preserved (exposed) due to overthrusting. The limestone megabreccia indicates enhanced tectonic activity causing repeated collapse of the platform margin, probably connected to the initiation of intraoceanic subduction within Neotethys followed by ophiolite obduction onto the eastern distal margin of the Adria.

斯洛文尼亚盆地南缘的中侏罗统石灰岩大型角砾岩

斯洛文尼亚盆地是中生代深水古地理单位，位于南部阿尔卑斯山东部与Dinarides之间的边界，记录皮埃蒙特－利古里亚和新特提斯洋域开放时的地球动力信号。在侏罗纪中部，南部与迪纳里克（亚得里亚海）碳酸盐岩台地相接，北部与朱利安海底高原相接。盆地南缘的特征是巴约西亚－巴松山（Callovian？）时代的几十米厚的沉积层序，其中以从迪纳里克碳酸盐岩台地中喷出的石灰岩巨型角砾岩为主导，并由泥石流沉积在脚趾上。斜坡沉积环境。它伴随着通过（高密度）浊流沉积的灰泥/谷物/堆积岩床。这个巨型角砾岩单元代表了托尔明组较低沉积的灰岩的近端等效物。碎石碎屑中的基质指示了卵石滩的再沉积以及盆地和斜坡沉积物的侵蚀。碎石碎屑体的年龄为诺里安至下侏罗纪，起源于（A）台缘边缘碳酸盐，即三叠纪边缘礁和下侏罗统砂滩浅层石灰石，（B）深层开放式或斜坡粗生物碎屑石灰石，以及（C）较早的盆地岩石。碎石裂变分析能够重建由于过度推覆而无法保留（暴露）的平台-盆地过渡带。石灰岩巨角砾岩表明构造活动增强，导致台缘反复塌陷，
